QDAVID J. BESSIE, OF SAN ANGELO, TEXAS.

AIR COOLER.

Application filed March 16, 1927. Serial No. 175,780.

This invention relates to means adapted to lower the temperature of living rooms for comfort, or of compartments for preserving food, and consists of a frame over which is draped a loosely woven fabric, means for supplying water to the fabric to keep the same moist, a fan for creating a positive circulation of air whereby the moisture is evaporated and the air cooled, and a float controlled pump for elevating and supplying the water to the reservoir into which the fabric dips and from which it derives the moisture.

While the drawings illustrate a preferred embodiment of the invention, it is to be understood that in adapting the means to meet specific needs and requirements, the design may be varied and such other changes in the minor details of construction may be resorted to within the scope of the invention as claimed, without departing from the spirit thereof.

For a full understanding of the invention and the merits thereof, reference is to be had to the following description and the drawings hereto attached, in Which,-

Figure 1 is a vertical, central, longitudinal sectional view of an air cooler, embodying the invention.

Figure 2 is a detail view of a portion thereof showing more clearly the float controlled pump.

Figure 3 is a vertical, transverse sectional view of the cooler.

Figure 4 is a detail view showing more clearly the float controlled, switch, whereby the circuit of the motor provided for operating the pump is closed and opened.

Corresponding and like parts are re ferred to in the following description and designated in the several views of the drawings by like reference characters.

The numeral 1 designates a suitable framework which may be of any open construction and dimensions depending upon the particular adaptation and use of the invention. reservoir 2 is located at the top of the framework and is open at the top and closed its bottom and sides, so as to hold a quantity of water. An ice box '3 is located Within the reservoir 2 and is adapted to receive ice, for cooling the water of the reservoir. A loosely woven fabric 4, or fine wire mesh, is draped over the framework and hangs along opposite sides thereof, as indicated most clearly in Figure 3.

This fabric dips into the reservoir 2 and lies against the bottom and sides thereof, as indicated most clearly in Figure 3. fabric 4 draws the water from the reservoir 2 and is kept in a moist condition so long as the reservoir contains a supply of water. Troughs 5 are provided at opposite sides of the framework for the lower ends of the fabric 4 to enter and discharge surplus moisture. A stiffening and reinforcing strip 6 is applied to the lower end of each side portion of the fabric to hold the same in proper position and prevent displacement of the lower ends from the troughs and thereby assure the drippings discharging into the said troughs.

A tank 7 is disposed to receive the drippings from the trough and when necessary Water from any source may be supplied to the tank 7. A pump 8 is associated with the tank 7 so as to draw the water therefrom and discharge it by way of a pipe 9 into the reservoir 2. An electric motor 10 is provided for operating the pump 8 and current is adapted to be supplied, thereto from a suitable source, the circuit including a switch which is adapted to be automatically operated by means of a float 11 to make and break the circuit. The switch includes a contact 12 and a member 13, the latter being pivoted intermediate its ends to a post 14, or other convenient support. A stem 15 projecting from the float 11 is provided with spaced stops 16 and 17 which are adapted to alternately engage the member 13 so as to make and break the circuit, whereby the motor 10 is controlled for operating the pump 8.

and rests with its open side in contact with' the bottom of the reservoir 2. y The air space enclosed between the walls of the box retains the cold and prevents the rapid melting of the ice which is placed upon the bottom of The V the reservoir or trough 2 and is enclosed by the box which receives the same.

The term fabric is used to include any woven material, such as textile, or wire, and of a nature to hold water in a lilrn which by evaporation cools the air. The device may he used in any place where the air is required to be cooled, such as hospitals, sick rooms, and places of public assemblage, including halls, churches, theatres, hotels and the like.

Having thus described the invention, I claim:

An air cooler including a framework of open construction, a reservoir at the top of the framework to receive Water and ice, troughs at opposite sides of the framework adjacent the bottom thereof, a fabric dipping, into the reservoir and extending along opposite sides of the framework and having its lowcn end terminating in the trougl'is, a tank disposed below the troughs to receive the drippings therefrom, a pump for drawing water from the tank and dispensing it into thereservoir, float controlled means aetuated by the change of level of the water in thetank to throw the pump into and out of action, and a fan disposed below the reservoir and between the depending portions of fabric to create a positive (.ll'ClllilbltHl of air.

In testimony whereof Iaflix my signature.
